Abstract

In this paper, design and fabrication of a diode pumped Nd:YAG laser using a new design of laser head and high beam quality factor is reported. Appropriate diode lasers are prepared. Driver circuit, which works at quasi continuous wave (QCW) mode is fabricated. This circuit has a tunable pulse repetition rate and input current. Heat distribution in the active material and output beam profile is simulated by LASCAD software. Output pulses with 14 mJ energy, 200 μs time duration, and 1 Hz pulse repetition rate are achieved. High beam quality factor with M 2 ≤ 1.08 is obtained.
